The Umkhonto SAM system was developed by Denel Dynamics for the SA Navy’s Meko A200 class frigates, and is in service in both Block 1 and Block 2 versions. The Block 2, with a range of 15 km, is also used by the Finnish Navy aboard its Hamina class corvettes and Hämeenmaa class mine layers. The Block 2 variant features a 3 km greater range and a seeker aimed at processing cluttered environments, especially in look-down mode. The Umkhonto has reportedly been selected by Algeria for use on its Meko frigates
